The material standard of A2-70 belongs to austenitic stainless steel, which has high tensile strength and corrosion resistance. A2-70 stainless steel fasteners, such as bolts and nuts, are widely used in various industrial fields, including machinery, construction, chemical industry, etc.
A4-80 belongs to the category of martensitic stainless steel. The mechanical properties of stainless steel fasteners of this material can be adjusted through heat treatment. It is a hardenable stainless steel.
The difficulty in manufacturing A4-80 fasteners is to ensure that their performance reaches the strength standard of 80, that is, the tensile strength is at least 800N/mm², which belongs to the high-strength bolt type. The processing difficulty of martensitic stainless steel is mainly concentrated in the mastery of heat treatment process, because the hardness is higher after quenching, and different tempering temperatures will affect its strength and toughness combination.
